ICE-MACHINE PRESS.

Specification of Letters Patent.

Patented Jan. 14, 1908.

To all whom it may concern:

Be it known that I, DANIEL L. Hommn, a citizen of the United States,residing at cw York, in the county of New York and State of New York,have invented certain new and useful Improvements in Ice-MachinePresses, of which the following is a specification.

. This invention is for the rapid manufacture of merchantable blocks ofice by the pressing and regulating of small particles of me into a solidmass.

-To enable a continuous operation, and great efiiciency in production, adouble acting hydraulic pressure cylinder and two ice presses arearranged in ahnement, or tandem, the presses being at each end of thepressure cylinder, so that the presses are fed-alter nately and the iceblocks are discharged alternately from each press, which results insaving much time as wel} as greatly increasing the output over thefori'i ier machines 'where only one press was operated by a pressurecylinder. There are other co-acting means which contribute to perfectthe operation, and which will be set forth in the speciiication.

The invention is illustrated in the accomanying drawings, in whichsimilar parts liear similar figures of reference wherever shown, in which Figure 1 is a side elevation. Fig. 2 is a top or plan view. Fig. 3,4 are enlarged views of the indicator roller and its support. Fig. 5 isa view of the valve for the ice presses, when open'. Fig. 6 is a view ofthe valve for the ice presses, when closed.

A bed plate 1 provides a common support for a double acting hydraulicpressure cylin der 2, and ice presses 3,4, one being at each end of thecylinder. The pressure cylinder has heads 5, 6 with stuffing boxes 7, 8,while. heads 9,10 with shilling boxes 11, 12 are provided for the innerheads ol'- the presses, their outer ends having vertically moving gates13, 14. Within cylinder 2 there is a )iston 15 with rods 16, 17extending thereirom-into the )resscs and connected to their rams 1h, 19.11 order to gain ready access to all the piston and rams, the presses2%, are placed away from cylinder 2 far enough to permit head '5 to bedetached. and moved over to head 9, and head .10 to be detached andmoved over to head ii, and with gate 12-;

moved up piston 15 may be moved to the open space between cylinder 2 andpress 3,

or by moving the opposite heads 6,. 9 and gate 14 piston 15 may be movedto the space between cylinder 2 and press 4. The movement of piston 15is controlled by a hydraulicvalve 20, for light pressures, and byhydraulic valve 21, for greater pressures, these valves being oi" any ofthe Well known constructions adapted to the purpose.

Under the presses 3, 4, near their outer ends, there are secured rotaryvalves 22, 23 which open and close the passage for the ilow of iceparticles from pipes 2+1, 25 to presses 3, 4 the passages being openwhen tlfie rams 18, 19 are at the inner end of their stroke. By placingthe valves 22, 23 under the presses any air which may be carried in withthe ice particles will be free to escape by the means provided, and willnot whiten the ice block, or revent its solidity.

is seen in the views, gate 13 has been moved up, by its odinder 26 toopen the end of press 3, ram 18 ms been moved by piston 15 to expel. anice block and valve 22 is closed while rain 19 is at the inner end ofits stroke, gate 14 is closed by its cylinder 27, valve 23 is open andparticles are flowing into press 4. Valves 22, 23 are automaticallyopened by the rams 18, 19, each valve being provided with a stem 28passing through a stuffing hex 29 and having thereto attached an arm 30connected to a rod 31.. As valves 22, 23 must rotate in the samedirections, in opening, and as rams 13, 1.9 move in oppo site directionswhen opening the valves, it is necessary to provide a different meansfor rain 18 to operate valve 22 from that which is used. by ram 19 tooperate valve 23, therefore, rod 31 of valve 22 for press 3 is attachedto a lever 32 with an intermediate or central fulcrum 33, and at itsopposite end lever CiJ-has thereto atiacl i cd a pin 34 which enterspress 2% and is pnshcl'l outward by rain 18 to put valve 22 into itsopen position, as seen in Fig. 5; press 4 is provided with a lcvcr 2. 3attached to rod Ill of its valve 23, the lever biting 'l'ulcruincd atits opposite end 36, and inicrlncdiately there is attached a pin 337which enters press. 4 and is pushed outward by rain 19 to put val e 23into its open position, as seen in Fig. 5; the rams overcomesprings Sfsfwhich are attached to levers 32, 35 which operate to close valves 22,2-3 when rams 18, 19 move away from pins 34, 37 to put the valves intothe position, closed, as seen in Fig. 6, the ports 39 being covered byrams 18, 19 before the valves are again opened.

After the ice block has been discharged, the movable parts will assumethe positions seen in press 4, where its gate 14 is moved down bycylinder 27 to close the press and ram 19 has moved to its innerposition Where it abuts pin 37, moving lever 35, overcoming s ring 38and opening valve 23 to permit t e' ice particles to pass into the pressthrough port 39; when tieram was atthe outer end of its stroke, to expelthe ice block, it covered )ort 39 into the press, as

seen in 6, so t at even should t 10 valve be disarranged, or inoperativeno ice particles could then pass into the press, this is an extraprecaution against any ice particles assing to the inner side of theram, making it possible for the ice particles to flow in between the ramand its gate. The operation of the rams and valves are alternate and intermittent, with an interval of time for the flow of ice particles tothe messes.

The ice particles are gathered from a tank (not shown) by a pump 40having a suction pipe 41 connected to the tank and a delivery pipe 42passing to a three way valve 43 connected to pipes 24, 25 heretoforedescribed. A hand wheel 44 is used by the attendant to operate valve 43to connect pipes 42, 24 and 42, 25 alternately, to permit the flow ofice particles to the valves 22, 23 I under the presses 3, 4. There isalso within easy reach of the attendant a handle 45 on a rod 46connected to a lever'47, iulcrumcd at 48, which operates a clutch 49 toconnect and disconnect sprocket wheel 50 to shaft .5101 pump 40 to startand stop the pump.

resses 3, 4, have eriorated linings, (l Patent 730,018,

June 2, 1903, the upper and side perforations in connection with pi es52, 53 will remove."

any air carried into t 1e presses with the ice particles, and thelower-perforations permit the escape of any Water, so that the ice blockis erfectly pellucid. I

11 order to enable the attendant to know the movements and exact(positions of piston 15, and rams 18, 19 an in ester is provided whichis composed of a roller 54 resiliently mounted on a stand 55 for rotarycontact with piston rod 17 and the contact is made slot 60 of theindicator plate 61 and to the Weight there is attached a pointer 62which points to double lines of 'graduations 0 to 24 1n reverse orderwhich enable the attendant to observe the strokes or movements of thepiston and rams, and their exact positions.
